To all whom Z1 may concern.'

Be it known that l, ANTHONY ivi. BERNARD, a citizen of the UnitedStates, residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful improvements in ReadyOpeners for Gasket-Sealed Containers; and l do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

rlhis invention relates to a sealing device for a container of the opentop or jar type and especially to a method and means for opening such asealed container. lt is a common practice to seal open-ended jars with acap comprising a flange disposed at the side of the container and spacedtherefrom, a compressible gasket being disposed between said fia-nge andthe side of the container for sealing the same. Such a flange iscommonly employed with a cover known as the double seal cover which alsocontacts the top edge of the j ar, but the use of such a flange is notlimited to such a cover. wWhen it is desired to open the jar it hasheretofore been necessary to gouge out a piece of the compressed gasketwith some implement in order to get hold thereof. After a hold issecured on the gasket or one of the broken ends thereof the same can bepulled from under the said flange and the cover removed. rlhis gasketremoving operation is quite troublesome and difhcult, it usually beingnecessary to place the jar on one side in order to effectively use animplement thereon.

It is an object of this invention, therefore, to provide a method ofsealing and sealing means for a jar by the use of which the gasket canbe removed with no trouble and little effort.

It is a further object of the invention to provide such a-meanscomprising a strip of flexible material which is placed around thegasket, said strip having a free projecting portion which can be pulledto pull the gasket from under the sealing flange.

These and other objects and advantages of the invention will be fullyset fort-h in the following description made in connection with theaccompanying drawings in which like reference characters refer to thesame Serial No. 570,422.

parts'throughout the different views. and in which, l

Fig. l is a view in side elevation of a sealed laf;

Fig. 2 is a view in vertical section thereof taken on the line 2-2 ofFig. l, as indicated bythe arrows; and

Fig, 3 is a partial similar vertical section on an enlarged scale.

Referring to the drawings, an open ended container or jar l is shownhaving thereon a sealing cover 2. The cover 2 extends across the topedge of the container and contacts therewith to form one seal andisfurther bent to have a flange 3 depending therefrom and spaced from theexterior of the container. A gasket 4, preferably of continuous annularform is disposed between the flange 3 and the side of the receptacle andcompressed by pressing inwardly or crimping in the flange 3. This formsa second seal for the jar. The covers 2 are usually placed in positionand pressed or crimped against the gaskets by a machine, although theoperation may be performed by hand. In order to provide means foropening the ar a strip of flexible material 5 is used preferably made ofthin fabric, which strip is passed around a gasket 4, as shown in Figs.2 and 3 and has its ends depending at the sides of the receptacle. Thestrip is placed in position with the gasket and when the flange 3 ispressed against the gasket the strip is pressed against the gasket and,being of thin fabric, does not interfere with the sealing operation, theseal being just as tight as if the strip were not used.

l/Vhen it is desired to remove the cover of the jar, instead of itbeing' necessary to gouge out a portion of the gasket 4 it is onlynecessary to hold the j ar and pull upon the ends of the strip 5, aportion of the gasket is thus pulled from beneath the flange 4 and thegasket can be quickly peeled or drawn from under said flange entirelyaround the j ar. The cover 2 can then be lifted.

From the above description it will be seen that applicant has provided asimple and eflicient method of sealing a jar using means by which thesealed gasket can be very easily removed and the cover then lifted. Thestrip of material merely hangs at one side of the jar while the same issealed or while the same is being handled in the trade. lf desired, theends of the fabric can, of' course be placed under any label which itmay be desired to add to the jar during the commercial handling thereof.

lt will, of course, be understood that varin ous changes may be made inthe method or in the form, arrangement and material of the apparatuswithout departing from the vscope of applieants invention, which, gen-yerally stated consists in the matter shown and deseribec and set :forthin the appended claims.

What is claimed is:

l. The method orP sealing an open top container comprising positioningla cover thereon having a flange spaced from the exterior of saidcontainer, placing a gasket between said flange and said Container,placing a strip of thin flexible material trans versely around saidgasket so as to depend at the side rolf said container and pressing saidflange against said gasket and strip to provide a tight seal.

2. A sealffor an open top container and opener therefor, comprising, acap having flange spaeedfrom the side of said container, a gasketcompressed between said flange and the container and the strip of thinkflexible material passed around said gasket and having a freelyextending portion whereby said strip oan be pulled to extract a portionof lsaid gasket from beneath said flange.

3. The method of sealing a jar consisting in placing a cap thereon, inContact with an annular gasket and placing a strip of thin flexiblematerial around said gasket, said strip having a freely extendingportion which can be pulled upon to remove a portion of said gasket frombeneath said cap.

4l. A sealing and opening structure for a jar comprising, a cover, agasket compressed between the same and the exterior of the jar, and astrip 0I" thin flexible material passing transversely around said gasketand having a freely extending portion at the exterior of the jar.

'5. A sealing structure for an open top Container comprising, a oapinelosing the top of said container and having a fiange projeetingdownwardly at the side thereof, a gasket compressed between said flangeand the exterior of said Container, andA a strip of flexible materialpassed transversely around said gasket in a plane extendingsubstantially at right angles to the annular plane of said gasket, saidstripbeing compressed with said gasket between said flange and containerand adapted to be pulled to draw a portion of said gasket fromunderneath said flange. v

lntestimony whereof I affix my sifrnature. l
